SHIELD FOR VEHICLE-TIRES.

Specification of Letters Patent.

Patented Mar. '7, 1911.

Application filed January 13, 1910. Serial No. 537,922.

To all whom it may concern:

Be it known that I, JosErnmN E. JosLIcN, a citizen of the United States,residing at Les Angeles, in'the county of Los Angeles and State ofCalifornia, have invented a new and useful Shield for Vehicle-Tires, ofwhich the following is a specification.

.This invention relates .to shields for vehicle tires which fit over theordinary pneumatic'tire forming a shoe therefor of greater wearingqualities than ,the tire itself and which form a protection for. thetire against puncture and wear.

One of the objects of my invention is to produce a shield of thecharacter described which may be made in sections adapted to interlockwith each other.

Another object of my invention is to pr o-' duce a shield of thecharacter described which is built up in sections adapted to fit overthe ordinary pneumatic tire and to be held thereon without attachment tothe other parts of the wheel.

Another object of my invention is to' produee a shield of the characterdescribed which is simple and economical 1n construction and which may ereadily attacheu the tire.

Other objects and advantages will appear as hereinafter described.

Referring to the drawings which show an embodiment of the invention:Figure 1 is a side elevation, partly in section, of'a vehicle wheelequipped with my invention. Fig. 2, is an enlarged transverse sectionalView on the line m w Fig. 1. Fig. 3, is an enlarged side elevation,partly in'section, of a portion of the shield. Fig. 4, is aperspectivelview of one of the units which form the shie d.

1 designates a vehicle wheel having a hub 2, spokes 3, and felly 4:. Thetire 5 consists of an outer casing 6 and inner tube 7, and is secured inany preferred manner to a rim 8 on the felly 4.

The shield 9 is made preferably of cast metal and consists of a numberof blocks or links 10 which together form a continuous tread for thetire 5. The inner surface 11 of the blocks 10 is rounded to conform tothe exterior of the tire 5, the sides 12 of the blocks 10 extendinginwardly over the tire approximately to the greatest transverse diameterof the tire.

The blocks 10 are made of interchangeable form, the tread portion13 ofeach block is provided at one end with a flat projection forming a hook14, the other end of the tread portion 13 is provided with a hollow lug15, the recess 16 therein conforming to the shape of the hook 14. Theends-of the blocks are made to conform to a radial line with the centerof the wheel, so .that when the blocks are assembled ashereinafterdescribed, the ends of the adjacent blocks fit against each other,thereby forming a continuous shield for the tire. Each ,block 10 isprovided at one end with extensions 17 on the "sides 12 which'extendover the joint 18 between the adjacent blocks, thereby preventingforeign substances from entering between the blocks and closures for theblock connecting means heretofore described. vided on the tread portion13 with projections 19 which extend outwardly a distance equal to theheight of the lugs 15. The lugs 15 and projections 19 form grippingmeans for the tire. The blocks 10 are locked togethcr by holding theadjacent blocks with the tread portion 13 of each block toward eachother.- 'lVith the blocks in this position the hook 14 of one block maybe inserted into the mouth of the recess 16 and upon turning the blocksup into their permanent positions, the hook 14 fits into the recess asclearly shown in Fig. 3 of the'drawing. The last two blocks 10 whichcomplete the shield are fastened together in the same manner as theother blocks hereinabove described. The tire- 5 is fitted within theshield, after which the tire is fastened to the rim of the wheel and theinner tube filled with air under pressure whichholds the tire againstthe inner surface 11 of the blocks, thereby holding the shield firmly onthe tire.

What I claim is 1. A shield for -a vehicle tire comprising a pluralityof links adapted to fit over the tread of the tire, each link comprisinga block having a tread portion, side walls on said blocks extendinginwardly over said tire, extensions on said walls extending over theoint between said blocks, and means for connecting said blocks together,said blocks also forming end forming a continuous imperforate shield forsaid tire, said extension on the side walls forming end closures for theblock conneoting means.

2. A shield for a vehicle tire comprising a plurality of links adaptedto fit over the tread of the tire and form a continuous impert'o1 ateshield for the tire, said links end closures for the block'connectingmeans,

said means extending outwardly from the tread 01' said blocks, andprojections on said blocks between said connecting means, saidconnecting means and said projections forming gripping means for saidshield.

In testimony whereof I have hereunto set my hand at Los Angeles,California, this 7th day of January, 1910.
